TLC5941-Q1中文资料具有像点修正与灰度 PWM 控制功能的汽车类 16 通道 LED 驱动器数据手册TI规格书

描述 Description

The TLC5941-Q1 device is a 16-channel, constant-current sink, LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink (dot correction), which both are accessible via a serial interface. This device features two fault diagnostic circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an over temperature condition.

The TLC5941-Q1 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an overtemperature condition.
